According to Berkshire's 13-F filing with the SEC, the company held just over 492-thousand shares of J&J as of September 30. That's a 95 percent reduction from the 10.3 million shares it reported holding as of June 30. The market value of the remaining holdings is just $34 million, down $682 million.

Berkshire's GE stock has been slashed to 588,900 shares. That's down 88 percent from just over five million shares three months earlier. That stake is now worth just under $12 million, down $88.4 million.

A few stocks were added to Berkshire's portfolio during the third quarter, but they all appear to have been purchased by one of Berkshire's new portfolio managers, Todd Combs or Ted Weschler. Their buying and selling decisions usually involve hundreds of millions of dollars of stock or less. When the stakes get above $1 billion, it's a sign Buffett himself was involved.

The biggest addition is Deere & CO. with almost 4 million shares worth $337 million.

The filing also shows Berkshire owned 1,248,901 shares of Precision Castparts at the end of the quarter. That stake is currently worth $216 million,

The smallest addition is Wabco Holdings with almost 1.6 million shares worth $92 million.

The filing shows that Berkshire now owns 400 million shares of Coca-Cola instead of the 200 million listed as of June 30. That increase, however, is the result of a two-for-one stock split during the quarter, and doesn't represent new buying.

The total value of Berkshire's reported U.S. stock portfolio was $75.3 billion as of September 30, up from $74.3 billion at the end of June.
